TT, do you mean a 38-10? The 39-10RP is a phonograph that was attached to a radio.

Have you done anything with the radio (like recapping it and checking resistors)? If the answer is no, then don't power it up again until you do.
Good luck.

OK, here's the 37-10 schematic. Have you recapped the set?

I have schematic and it has been re-capped. Changes per #269 revisions were made.

The reason I asked about pics is I wanted see if the power transformer is original to the set among other things.

Here are some instructions for adding pictures. I added the link to the schematic to make it easier for folks to help you.

Yes, I use dropbox. You put the pictures you want to share in the "public" folder.
